O2 Sensor & Poor Cold Idle Issues

[Hahnsb2]

Getting a little testy there aren't we Hahns? And, you don't have to argue about it at all, just move on, no one is holding a gun to your head. You don't get around much if you haven't seen my posts in other areas.

I'm not talking about a sandblaster. I know that when air is moved it drags a lot of air with it. Some systems are designed to use this additional air flow, but this is an entirely different situation.

I have worked on hundreds of these systems, and have never seen a problem with small leaks. Some manifolds crack quickly without detrimental affects. Go find a manifold that is not cracked for a 92 Toyota Corolla 4 cylinder, or Chevy Prism, and other such models. Kind of hard to find, and the cars run fine, but the noise drives you nuts. Also, these vehicles still pass Texas state emissions inspection which is one of the more stringent.

As I stated before, two of my vehicles currently have exhaust leaks, and have given me no poblems.

Take a chill pill dude, life is too short, and at 19 years old, wait until you have a little experience with this sort of thing before trying to give me a dressing down. shady

I never said it will cause a problem. I certainly think it's possible. The new 6.4 PSDs (and the new Dmax too I think) have slots cut into the exhaust to draw in cool air to cool the hot ass exhaust (caused by those dumbass DPFs) to prevent burns. I know in this state they won't pass vehicles with exhaust leaks. Unless the exhaust it super restrictive I think it can draw in air through a leak.
